A Case of Vocal Cord Dysfunction Diagnosed as Bronchial Asthma, That was Improved by Psychosomatic Therapy

: A 19-year-old psychologically disturbed female was admitted to our hospital because of intractable dyspnea and wheezing for twenty two months. She had been diagnosed as having asthma and had received several medications including steroids before admission to our hospital. According to our clinical observations, she was considered not to have asthma because neither FEV1.0 nor PaO2 was decreased during the periods of wheezing and FEV1.0 was not changed by inhalation of bronchodilators, although she had a family history of allergy and false bronchial hyperreactivity by asthograph. On physical examination, diffuse wheezing was heard mainly over the larynx during inspiration at the times of dyspnea. There was flattening of the inspiratory flow-volume loop during wheezing. Bronchoscopy performed during an attack confirmed that wheezing was due to adduction of the vocal cords throughout the respiratory cycle. Therefore, this case was diagnosed as vocal cord dysfunction. Her symptom was considered to be a form of conversion reaction derived from her unhappy past history. Following psychosomatic therapy, all of her medications became unnecessary. She understood the mind-body relationship of her condition, and learned to achieve self-control.
